InGaP/GaAs/InGaAs Multijunction Flexible Photovoltaics With Chemical Robustness and Radiation Hardness for Unassisted Electrocatalysis and Space Applications

Advanced Energy Materials, EarlyView.
A flexible InGaP/GaAs/InGaAs triple‐junction platform encapsulated with ultrathin glass enables unassisted electrocatalysis and space applications by providing robust protection against chemically aggressive and radiation‐rich environments. This work establishes a unified III–V multijunction photovoltaic platform that bridges space photovoltaics and ...

Dialkyl Ethers and Sacrificial Zinc: Oxide Synthons for Calcium tert‐Butoxide Formation

Angewandte Chemie, EarlyView.
When treated with dialkyl ethers, [(BDI)Ca‐μ‐H‐Zn(t‐Bu)2(η6‐C7H8)] (BDI = HC{C(Me)NDipp}2 initiates a sequence of twofold ether dealkylation and oxide sequestration as tert‐butoxide in a process predicated on a combination of extreme basicity and a cooperative redox process administered by the dissimilar constituent metals. (Generative AI (ChatGPT) was

Hydro- and deutero-deamination of primary amines using O-diphenylphosphinylhydroxylamine

Nature Communications
While selective defunctionalizations are valuable in organic synthesis, hydrodeamination of primary amines poses challenges. Deuterodeamination, analogous to hydrodeamination, presents even greater difficulties due to its frequently slower deuteration ...

Deuterium Labelling of L-Tyrosine with Raney Alloys in Alkaline Deuterium Oxide Solutions

, 1997
The synthesis of deuteriated L-tyrosines with Raney alloys in alkaline deuterium oxide solutions, involving reductive debromination of brominated L-tyrosines and hydrogen-deuterium (H-D) exchange of L-tyrosines, without causing racemization, is ...

Multi‐modal Operando Analysis of Lithium–Sulfur Batteries: A Comparative Study on the Influence of Electrolyte Composition

Advanced Energy Materials, EarlyView.
The influence of different electrolytes on Lithium–sulfur batteries is investigated. Multimodal operando analysis, including Raman, UV–vis, and Impedance spectroscopy is used to study degradation mechanisms. The solubility of polysulfides in the electrolyte is crucial for battery capacity and lifetime.

Nitrogen Radical Photocatalysed Reduction of Nitrous Oxide

Angewandte Chemie, EarlyView.
This work offers the first example of reduction of the potent greenhouse gas N2O to the benign products N2 and O(Bpin)2 using a nitrogen‐based catalyst. The active catalyst is shown to be a nitrogen‐based radical which operates under photocatalytic conditions.

Insights from quasi-in situ cryogenic-transfer atom probe tomography for analyzing hydrogen diffusion in metallic alloys

npj Materials Degradation
Understanding hydrogen embrittlement mechanisms requires insights into nanoscale hydrogen isotope segregation in materials. Cryogenic-transfer atom probe tomography (APT) can provide this insight, if the sample exposure is precisely controlled. Therefore,

Skeletal Muscle Mitochondrial Protein Synthesis and Respiration Increase With Low-Load Blood Flow Restricted as Well as High-Load Resistance Training

Frontiers in Physiology, 2018
Purpose: It is well established that high-load resistance exercise (HLRE) can stimulate myofibrillar accretion. Additionally, recent studies suggest that HLRE can also stimulate mitochondrial biogenesis and respiratory function.
